  • Heat exchanger suitable for a refrigerant evaporator
    Patent number: 5896916
    Abstract: In a heat exchanger made of stacked tubular elements, the tubular elements are formed from pressed plates bearing on one another. The plates enclose between them a cavity which is connected via corresponding orifices to the cavity of the tubular element adjacent in each case. In order to fix the stacked plates in their position and reliably prevent slipping along the tubular element plane, all the plates of the heat exchanger are provided with a congruent fixing orifice, into which a fixing rod can be inserted. A method for manufacturing the heat exchanger is also disclosed.
